Patent CA-2334829-A1 (CA)
Title: Filtering plant for waste water
Inventor: PEDERSEN NILS ERIK
IPC: C02F3/30
Filed: 1999-06-10
Abstract: This invention comprises a purification plant for purifying waste water and recycling water from a small group of households, agricultural units, cabins  and the like. If the plant receives only grey water, the plant should purify  it to such an extent that the water can be re-used for watering, washing, flushing of toilets, etc. If the plant receives black water, the plant shoul d purify it to such an extent that the effluent can be safely discharged into the environment. The plant is divided into three main parts; a sludge interceptor, a main filter with vertical unsaturated aerobic flow at the top  and saturated anaerobic flow at the bottom of the filter, and a final filter  with horizontal saturated anaerobic flow. As a final treatment the water is disinfected in order to remove bacteria. The filter plant is equipped with o ne or more buffer zones and overflow pipes between the main parts in order to give the plant the capacity to absorb extraordinary loads without untreated waste water running out into the environment.

Title: Ultra-highspeed packet transfer ring network
Inventor: YAMABAYASHI YOSHIAKI
IPC: H04B10/291
Filed: 2001-02-26
Abstract: In the present ultra-highspeed packet transfer ring network, an add/drop multiplex type node apparatus adds an optical packet to the optical fiber transmission path by preparing a label signal containing information on an address of a destination node apparatus or a routing to the destination node apparatus, and outputs time-sequenced signals to the optical fiber transmission path by multiplexing the optical packet and the label signal by means of wavelength or polarization multiplexing. The add/drop multiplex type node apparatus also receives a label signal by separating and extracting the label signal from the optical fiber transmission path, and determines whether to drop an optical packet corresponding to the label signal to its own node apparatus or to pass the optical packet through with reference to an address or routing information contained in the label signal, and operates an optical switch accordingly. Also, in this ultra-highspeed packet transfer ring network, each node constantly monitors label signals so as to detect any fault developing in the transmission path and to divert the optical packets around the fault. Also, the ultra-highspeed packet transfer ring network enables optical packet compression using a simple circuit by modulating the optical pulses separated by an optical divider with respective data, and multiplexing the modulated pulses again. Also, highspeed optical packet decompression is achieved using a simple circuitry by converting the input optical packets in an OTDM/WDM conversion circuit to different wavelengths and inputting these waves in a wavelength-dependent delay circuit.

Title: Apparatus for precisely dispensing small amounts of ultra-fine particles
Inventor: GRACE JOHN R
IPC: B01F23/30
Filed: 1999-08-13
Abstract: A dispensing apparatus is provided for the dispensing of fine particles on a dry basis in a reproducible manner, using two-stage fluidization of particles.  The first stage (20) is preferably a fluidized bed with a freeboard on the top, but possibly a dilute-phase fluidized bed with a dilute gas-solids suspension filling the whole chamber, and the second stage (30) is a dilute gas-solid suspension fluidized bed. The second stage receives particles drawn from suspended particles in the first stage (20), and produces a very uniform dilute suspension of those particles, from which very accurate quantities can then be drawn via withdrawal ports (31), into a collection area (34) for dispensing therefrom. Optionally, multiple second-stage chambers can be provided, each drawing suspended particles via a separate conduit (15) from the first-stage chamber (20), which is potentially much larger. Similarly, there could be multiple withdrawal ports (31) from each second-stage chamber, to increase the total number of dispensing points (34). Withdrawal is preferably by time-controlled opening of the withdrawal port or ports, resulting in accurate dispensing proportional to the length of time.

Title: Method for controlling a switching system
Inventor: RENGER WOLFGANG
IPC: H04Q3/545
Filed: 1999-08-02
Abstract: The invention relates to a method for controlling a switching system which comprises a central control unit (MP) and a plurality of peripheral devices.  According to said method, one of said peripheral devices (AE) transmits a request message (mdg) to the control unit (MP) which performs actions (ak1, ak2, akn) of said switching control device based on said request message. If said actions are successively completed, a corresponding completion message (dfn) is transmitted to the concerned peripheral device. Each request message (mdg), which is opened by a peripheral device (AE) and whose completion message has not arrived yet at the time of transmission after a predetermined stand-by time (tw), is transmitted back to the control unit. Said process is repeated until a corresponding completion message (dfn) is received. The control unit (MP) ignores the actions to be performed which are related to a request message (mdg) when these actions have already been completed by previous request messages.

The container is particularly suitable for separating and compacting recyclable materials due to the provision of a longitudinally extending diagonal partition. The container has a pair of refuse receiving buckets preferably adapted to be raised into alignment with apertures in the front wall of the container. Recyclable materials, sorted by type in the buckets, are then moved into the container by a compactor blade in each bucket. Discharge of the materials is facilitated by providing for swinging movement of the partition prior to the vehicle being in the dumping position. The partition is extensible so that when positioned diagonally with respect to side walls of the container, the partition extends to the discharge end of the container.

Title: Network for telephony and data communication
Inventor: BINDER YEHUDA
IPC: H04L12/56
Filed: 2000-03-02
Abstract: A local area network using the telephone wiring within a residence or other building simultaneously with telephony signals. The local area network uses high pass filters to access the high-frequency band across the media, whereas the standard telephone service uses low pass filters to access the low-frequency voice /  analog telephony band across the same media. The elec-trically-conducting media connecting telephone / data outlets are split, or separated at each outlet, and the outlets are modified to provide access to both ends of the resulting segments. The low pass filters at each segment end join the segments together, allowing analog telephony signals to travel throughout the network, thus supporting normal telephone service. The high pass filters at each segment end are connected to modems or other Data Communication Equipment, thus supporting data communication networks of various topologies, including point-to-point topologies.
